4) Project Title: West Bank Wastewater Assimilation Plant Entity/Individual Nominating the Project: St. James Parish Council Contact Information: Mr. Jody Chenier St. James Parish Council P. O. Box 106 Convent, LA 70723 Phone: (225) 562-2262 Fax: (225) 562-2279 jody.chenier@stjamesla.com Total CIAP Funds Proposed: $1,488,760.84 Parish CIAP Funds Proposed: $1,488,760.84 State CIAP Funds Proposed: $0 Infrastructure Funds Proposed: $0 Fiscal Year CIAP Allocation: $455,700.00 (FY2008); $386,760.42 (FY2009); $646,300.42 (FY2010) Description and Location of Project: The St. James Parish Council plans to construct a wetland assimilation treatment plant on property owned by the Parish Council in Vacherie, Louisiana. The plant will collect wastewater from secondary treatment modules and pump the wastewater to a sediment pond area. The nine acre pond will discharge into 2,400 acres of forested wetland areas that will directly affect the swampland composition and structure. The effluent discharge will be controlled to maximize sediment discharge and improve water quality. The project will use proven scientific research and analysis to provide a wetland wastewater strategy to promote wetland growth and survival. The project will provide low cost benefits to St. James Parish residents and businesses while improving water quality and enhancing deteriorating wetland areas. Unlike conventional tertiary treatment and filterization, the wetland assimilation process reduces the need for chemical treatment and allows for a more natural system, which provides for value added wetland production and absorption. Additionally, the use of a wetland assimilation process will provide a wetland fertilization source, as well as the removal of excess nutrients, especially nitrogen and phosphorus. The wetland treatment process provides needed sediment and nutrients for the protection of wetlands, wildlife habitat, and forest regeneration. Presently, little or no cypress regeneration occurs, leaving poorly developing relics. Additionally, areas where there were once dense stands of cypress and tupelo are becoming open areas lacking trees. St. James Parish will match existing sewerage construction funds to develop a sewer line system to connect all of the surrounding (Vacherie) area into this wetland enhancement project. The project will provide a means to fully integrate the sewerage treatment needs of all businesses and residents in the surrounding area. 204
St. James Parish will pay for the material and secondary treatment plants needed to treat the residential and commercial wastewater. Through the approval of a municipal sewerage tax, the parish is proposing to spend $16.9 million to install the needed collection and transportation systems. The parish will then require a full treatment implementation program to eliminate discharges into the Mississippi River and other water bodies within the parish. The proposed assimilation plant on the west bank will discharge into the Coteau Chevreuil freshwater forested wetlands. The initial targeted population of the project is approximately 5,500 persons. The proposed oxidation pond has a design capacity of 2.0 million gallons per day and would provide beneficial discharge to approximately 2,300 acres. The property is in the process of being purchased by St. James Parish and will, therefore, become publicly owned. The Parish plans to discharge the effluent evenly along the northern edge of the receiving wetlands and allow the natural hydrological gradient of the basin to sheet flow the discharge into the entire target area. This major wetland area of mostly flooded cypress and tupelo swamp will be the target area for the nutrient rich secondary treatment effluent. The effluent will promote vertical accretion through increased organic matter production and deposition. Similar wetland assimilation projects within the region have demonstrated increased accretion rates by a factor of three. It is anticipated that we will increase mineral matter accretion by 30% and organic matter by 50% within the target area. In an effort to accurately measure the increased production of vegetation and wetland habitat, the Parish will conduct initial base line information and undertake bi-annual data collection to measure the overall success and wetland benefits achieved through the wastewater assimilation process. Project Type: Authorized Use 1 Project Justification: Poor water quality and water stagnation are serious threats to wetland habitat. Because swamps in the Barataria Basin have been isolated from the Mississippi River, which was their primary source of water, sediments, and nutrients, the wetland areas continue to decline. The use of a wetland assimilation process will provide for increased productivity and regeneration of cypress and tupelo swamps, an increase in sediment accretion, and an increase in dissolved oxygen, as well as a reduction of nutrient concentrations in river water. The proposed project will directly create wetland habitat, reduce wetland loss rates in this area, and provide sustainability to the swamps in the face of long-term subsidence. 205
